LEASE-ROD.

SPECIFICATION forming part of Letters Patent NO. 624,658, dated May 9,1899. Application filed January 26, 1899. Serial No. 703,413. (Nomodel.)

T0 at whom it may concern:

Be it known that I, HAROLD KELLY, a citizen of the United States,residing at Biddeford, in the county of York and State of Maine, haveinvented certain new and useful Improvements in Lease-Rods; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in lease-rods, and the same isillustrated in the accompanying drawings, in which Figure 1 is aperspective View of so much of a loom as is necessary to show theapplication of my improved rods thereto. Figs. 2 and 4.- are anelevation and cross-section, respectively, of a lease-rod. Figs. 3 and 5are an elevation and cross-section, respectively, of a difierent form orshape of lease-rod. Fig. 6 is a sectional view of the adjustablerod-holder, and Fig. 7 is an end View of the holder.

Same letters of reference refer to like parts.

The warp-threads when they leave the beam are frequently stuck togetherby reason of the sizing or interlocking of fibers or knots in thethread, and when separated by the usual lease-rod threads are inconsequence often broken, causing much delay and imperfection in theWoven goods.

The object of my invention is to obviate these difficulties.

In said drawings, A represents the frame of a loom; B, the beam; 0, thewhip-roll, and D the warp.

My invention relates particularly to that one of the lease-rods nearestthe beam.

It consists in a rotatable rod.

It further consists in means for imparting a rotary motion to said rod.

It further consists in means adapted to render the rod quickly andeasily mounted in and dismounted from its sup orts.

To these ends I secure to either side of the -frame upright standards E,with suitable horizontal bearings F at the top. Mounted in saidhorizontal bearings are shafts G, having on the ends thereofsocketed'holders H, adapted to receive and support the ends of the rod.Said rod may be rotated in any convenient manneras, for example, by abelt I, passing over a pulley J on shaft G and a pulley K on shaft L.

It is important that the rod may be quickly and easily inserted andremoved from the warp. I therefore make one of the support ing-shaftscapable of longitudinal movement sufficient to releasethe end of the rodfrom the socket in the holder. This construction I have illustrated inFigs. land '7. I The shaft upper and lower threads on the-rod passesthrough a longer or shorter dimension of the rod. The rod may thereforebe of any shape in cross-section except circular. The shapes shown inFigs. 3 and 4 are examples in which the longer and shorter dimensionsare marked. It will be evident that the cross-sectional shape of the rodmay be indefinitely varied without departing from the spirit of myinvention. The supports which carry the rotatable holders canbe adjustedvertically by moving the standards up or down in tubular brackets S,secured to the sides of the frame, and may be held in any desiredposition by set-screws T, thus increasing or diminishing the tension onthe warp. It will also be evident that the manner of supporting the rodand the means for imparting a rotary motion to the rod may be varied atwill Without departing from the spirit of my invention, the leadingfeature of which is the rotation of the rod next the beam, said rodhaving unequal diameters.

The operation of my improved lease-rod is as follows: The warp-threadsconstantly un- I the whip-roll. side, and likewise the tension,

thereby more gradually separating the threads and rendering them lessliable to be broken.

Having thus described my invention and its use, I claim .1, In a loom, alease-rod, means for supporting said rod independently of the warpthreads and means for imparting a rotary motion to said rod.

2. In a loom, rotatable holders, a lease-rod mounted therein, one holderbeing held yieldingly against longitudinal movement and means forrotating said rod.

3. In a loom, rotatable holders, a lease-rod supported therein, meansfor rotating'said holders and rod, said rod having diameters of varyinglength.
